"The group is expected to deliver a standard system makers can implement in products before June 2013." So here we are, have they delivered a standard?

There is a clear differentialtion in XAUI Ethernet as well as 10G Ethernet between cables and backplanes by the use of similar but different standards. The same differentialtion between cables and backplanes can be maintained in PCI-X. The semiconductor technologies in all cases of multi-Gigabit serial are similar. I see no problems.

It is not only Apple using it, also Sony has announced to use it: e.g. see http://www.extremetech.com/computing/88370-sony-vaio-z-thunderbolt-price-macs-look-cheap

TB is Apple pushing Intel for a proprietary interface. As such I only expect to see it on Apple products. It will linger on there but will not catch on in the WinTel domain.

Thunderbolt is not intended to eliminate USB 3.0 as an interface. TB is really only about connectors if you think about it. It muxes existing PCIe and DP signals, sends them out over an active cable, and then the peripheral demuxes the signals and uses either PCIe or DP as dictated by the application. TB does not provide any more BW for the IOs - it uses existing BW. Now cabled PCIe does offer a higher BW pipe, but as many have pointed out already, it has been around for years and it has done nothing to eliminate USB as an I/O. Both TB and cabled PCIe offer some intriguing options for docking solutions for small form factor devices such as tablets and NetBooks. Figuring out how to use this for charging the devices is critical as well - and an area where USB is used almost exclusively today. Neither PCIe nor TB will ever be used for keyboards/mice/etc. directly connected to a device. Therefore USB 3.0 with its backwards compatibility to support these type of low BW devices as well as 5Gb transfers to flash drives makes it ideal for stand alone box IOs.

@jbreher: Cabled PCIe is not just an idea, has been a reality for years, so the evolution to the next generation will be smooth. In comparison, TB has to start from 1.0. Many vendors today make PCIe cables, both copper & fiber (One Stop Systems, for example): http://www.onestopsystems.com/accessories.php One Stop also makes PCIe Gen 2 switches that are available today. The 3m limitation will confine the applications to most top-of-rack applications. As long as there is an uplink from the rack to the next layer of switching, this shouldn't be an issue.

If you have missed this blog:http://www.semiwiki.com/forum/content/390-will-thunderbolt-kill-superspeed-usb.html you should have a look at it! It clearly explains that TB is just a way for Intel to capture a new chip market, the TB Controller, by using existing technologies (PCI Express and DisplayPort) which are served by other chip makers and their partners IP vendors (for PCIe PHY & Controller, same with DP)... In other word, ThunderBolt is a way for Intel to kill their competition, make Apple happy... and eventually kill SS USB. Will it really happen? I guess (and I hope) NOT!

If thunderbolt replaces the PCI express inside the chips, then probably the industry will move toward this slowly in the future.

Multiple standard trying to find their place in both board to board and cable interface is really confusing. USB 3.0 will no more required if PCIe also comes to cable.

The length is my major concern. ExpressCard does give the capability to plug in external cards, but it's generally not used to extend across the room. This isn't a big deal for an interface designed to do that (i.e. USB) but it can be problematic for backplane interfaces. Larry M.
